AUTOMATIC REGULATOR FOR WIND-WHEELS.

SPECIFICATION forming part of Letters Patent No. 631,725, dated August 22, 1899.

Application filed April 15, 1899. I Serial N- 713,168. (No model.)

To all whom it may concern:

Be it known that I, KNUD K. LEROL, Jr., a citizen of the United States, residing at Newburg, in the county of Fillmore and State of Minnesota, have invented new and useful Improvements in Automatic Regulators for Windmills, of which the following isa specification.

My invention relates to automatic regulators for windmills; and its object is to provide an improved construction of the same by which when the water in the tank rises to a predetermined level the windmill will be thrown out of gear and the pump stopped and the windmill thrown into gear and the pump such level.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure l is an elevation, partly in section, of a portion of a windmill and tank provided with myimprovements. Fig. 2 is a detailview showing the lever and pawl operated by the float. Fig. 3 is a detail view of the ratchet-wheel. Fig. 4 is a detail perspective view of the lever connected with the float.

In the said drawings the reference-numeral 1 designates the lever for throwing the windmill in and out of gear, and which may be of any ordinary or suitable construction.

The numeral 2 designates one of the horizontal beams of the windmill, to which is secured a plate 2, to which is pivoted a weighted wheel 3, having a number of ratchet-teeth 3 and provided on its inner face with pins 4 and 4. On its outer face said wheel is provided witha pin 5, with which is pivotally connected a rod 6, provided with a rope or chain 7, which passes around a pulley 8, journaled to said beam and to a bracket 9, secured thereto. This cord or chain is also connected with a vertical rod 10, having a clevis 12 at the upper end, adj ustably connected with one end of the lever 1. Also pivoted to said plate 2 is a lever 13, formed with a number of holes 14 and provided with an arm 15. Connected with this lever is a rope or chain 16, passing around a pulley 17, which rope is provided at its lower end with a float 18, located in the Said lever 13 is provided with a tank 19.

7 weighted arm 20, and the plate 2 is provided with an arm 21 above the arm 15.

The numeral 23 designates a pawl pivoted to the plate 2, the arm 21 limiting the movement of the lever 13 by coming in contact with the pin to which said pawl is pivoted.

The numeral 25 designates the weight of the ratchet-wheel.

Located at one side of the ratchet-wheel is a vertically-movable bar 26, which works in brackets 27 and is connected with the pumprod, so that as the latter is moved up and down by the windmill it will move the ratchetwheel. Upon the side adjacent to the ratchetwheel said bar is provided with a lug 29, with which is pivotally connected a catch or dog 30, adapted to engage with said ratchets.

The operation is as follows: The parts being in the position shown in Fig. 1, the windmill is out of gearand the pump stopped, the pin being above the dead-center and pin 4 being engaged with the arm 15, so as to lock the ratchet-wheel. WVhen the water in the tank falls below the predetermined level, the float will fall, operating or throwing back the lever 13 and disengaging the arm from the pin 4. The pull of the lever 1 will now turn the ratchet-wheel until the pin 5 is at the dead-center, or rather just above the same, and the pin at engages with the arm 15 of the lever, locking the ratchet-wheel in position. The windmill will now be thrown in gear and the pump started. When the water in the reservoir again reaches its proper level, the float will be elevated, allowing lever 13 to fall by the weighted arm and releasing pin 4. The weightof the ratchet-Wheel will now cause it to pass the dead-center, so that the first notch of the same will be engaged by the catch or dog 30 of the vertically-movable bar, which will turn said ratchet-wheel step by step until it has assumed its normal or firstmentioned position. This movement of the ratchet-wheel will operate the lever to throw the windmill out of gear and cause the pump to be stopped. The purpose of pawl 23 is to prevent backward movement of the ratchet- Wheel being turned by the bar.

Having thus fully described my invention, what I claim is- 1. In an automatic regulator for windmills, the combination with the operating-lever, the

rods and rope or chain connected therewith, the pulley and the weighted ratchet-Wheel with which one of said rods is connected and the pins on the inner face of said ratchet- Wheel, of the weighted lever, the arm thereof adapted to engage with said pins, the tank, the float connected with said lever, the pawl adapted to engage with said ratchel-wheel and the vertically-movable bar provided with a pivoted catch, substantially as described.

2. In a regulator for windmills, the combination with the operating lever, and the ratchet-wheel connected therewith provided with pins in its inner face,of the tank, the float,
